General description

Bis-tris methane, also known as BIS-TRIS or BTM, is a zwitterionic buffering agent widely employed in biochemical and biological research. It functions effectively in aqueous solutions within a pH range of 5.8 to 7.2 and demonstrates minimal shifts in its dissociation constant. Further, it can be used as a substitute for the highly toxic buffer cacodylate and is also recognized for its ability to form complexes with different metals.

Application

Bis-Tris has been used :
  • as a buffer for Electrophoresis[1]
  • as a component of transfer buffer for Western Blotting[2]

Features and Benefits

  • Suitable for Biological and Biochemical Research
  • Effective Buffering from pH 5.8-7.2 (25 °C) with a pKa of 6.5 (25 °C)
